High-performance liquid chromatography of the anti-tumour agent triethylenethiophosphoramide and its metabolite triethylenephosphoramide with sodium sulphide, taurine and o-phthalaldehyde as pre-column fluorescent derivatization reagents.

The method described is based on the reaction of triethylenethiophosphoramide (ThioTEPA) and triethylenephosphoramide (TEPA), through their ethyleneimine groups, with sodium sulphide, taurine and o-phthalaldehyde to give fluorescent products, and separation of the derivatives by reversed-phase high-performance liquid chromatography. The method was successfully applied to the determination of ThioTEPA and TEPA in rabbit plasma samples after clean-up with an Extrelut 3 column. The recoveries of ThioTEPA and TEPA from plasma were 66.1-80.3% and the limits of determination in plasma were ca. 10 and 20 ng/ml, respectively.[1]
